ActiveCN114327518Bprevent copyingavoid crackingEngineeringKey storage
The embodiments of the present invention provide a firmware storage method, a firmware reading method, a device, a chip processor and a storage medium, and relate to the field of chip technology. Applied to a chip processor, the chip includes a configuration area, an operation area and a backup area. The chip processor performs a read or write operation on the configuration area, the operation area and the backup area, and the configuration area is prohibited from being read by an external device. The method includes: when the chip is connected to a burning tool for communication, erasing the data stored in the operation area, and obtaining the original firmware burned by the burning tool. Automatically randomly generate a key and store the key in the configuration area. Based on the key and the compression algorithm built into the chip processor, perform compression and encryption operations on the original firmware to obtain a compressed file. The original firmware is stored in the operation area, and the compressed file is stored in the backup area. In this way, by setting the chip processor, the backup area and the operation area to store the firmware, the problem of the chip being cracked can be effectively prevented.
